One day, a spectacular picture popped up in my brain. It was an image of abandoned TVs being played as musical instruments on a street in a town. Using this image as a starting point, I set up the same number of tube televisions and PC-controlled video decks correspond to the number of notes in a musical scale to create a set of keyboard percussion instruments. Catching the electromagnetic waves from TV tubes by using body(connected to guitar amplifier directly) produces primitive and cosmic electrical music.
